Perhaps you should spend some time looking for a better text editor
for your OS. :) When the current tools I use does not give
satisfactory progress in what I'd like to do, I replace the tool(s).

Are you sure you fixed ALL of the offending lines containing
strtolower? This is what Notepad++ returns when I search for
"strtolower":

Given the above filenames, that pretty much takes care of all CSS...
Searching without file filters gives this in addition to above:
Search "strtolower" (51 hits in 30 files)
H:\data\Downloads\dev\PHP\htmlpurifier-4.4.0\docs\dev-code-quality.txt

Line 13: a lot of strtolower() calls, no legit casing

Line 1006: <li>...convert case (strtolower, strtoupper,
ucfirst, ucwords)</li>
Line 1019: <code>strtolower</code> (HTML Purifier uses this function.)</p>
Those above 2 filenames seems rather interesting... Then there's the
csstidy search for strtolower:
